Methods for the computation of surface deposition velocities of sulphur and nitrogen dioxide and also sulphate and nitrate particles are derived. These methods may be used in studies of long range (mesoscale and regional-scale) transport of pollutants. The influence of friction velocity and stability of the atmosphere on the aerodynamic resistance is discussed. The "standard" deposition velocities which consist of the surface resistance and resistance of the laminar sublayer adjacent to the surface, are estimated from the literature. Mean values of dry deposition velocities for some terrain categories, useful in long range transport models, are proposed.
